Thank You, Preserve VolunteersVital to helping us fulfill our mission, our volunteers are the heart and soul of Bowman’s Hill Wildflower Preserve. Each fall, we have the privilege of recognizing and thanking our dedicated, talented and generous volunteer team. On Nov. 12, 2018, the annual Volunteer Recognition Brunch was held at Thompson Memorial Presbyterian Church to celebrate those who contribute their time and talents to the Preserve.

In 2018, our volunteers donated over 12,000 hours at the Preserve. Whether through supporting Preserve staff, keeping the property pristine, attending to our seeds and plants, greeting the public, running programs or fundraising, their contributions were immeasurable. With their help, we were able to accomplish much—including restoring water flow to the Founders Pond and replanting it, establishing the Universal Access Trail, adding new office space in the Prop House, repairing the creek gates, preparing Aquetong Meadow, adding aquatic beds to the nursery along with growing beds for

specialty plants, working with Friends of Thompson-Neely Grist Mill to restore the Mill Race and reaching over 4,000 people through our education programs.

To help us honor our volunteers, several community sponsors donated or discounted goods. Special thanks to Barnes Arboretum, Brandywine Conservancy & Museum of Art, Bucks-Mont Party Rental, Colonial Farms, Crossing Vineyards and Winery, Grounds for Sculpture, Longwood Gardens, McCaffrey’s Markets, Mt. Cuba Center, Newtown Theatre, Owowcow Creamery, Riverside Symphonia, Rojo’s Roastery, Shady Brook Farm, Triumph Brewery, Tyler Arboretum and Zebra Striped Whale.

SPRING 2019 | VOLUME 26, ISSUE 1

Director’s MessageThe Preserve is beautiful at any time of year, but spring is truly special. Our guest book is filled with testimonials from people from all over the world who come to see our abundant display of spring ephemeral wildflowers.

It begins with the first wildflower to bloom—the beautiful and delicate snow trillium—that pushes its brave face through the leaf litter and snow to welcome the first day of spring. Our snow trillium persists on a limestone outcropping that Dr. Edgar Wherry, one of the Preserve’s founders, constructed in 1936.

More evidence of Dr. Wherry’s work can be found during the spring season along the Evergreen and Fern Trails, where two-leaved toothwort blooms in several large drifts. You will also find his work along the Medicinal Trail, formerly part of the Harshberger Trail—named after Dr. Wherry’s botany professor at the University of Pennsylvania.

After the snow trillium’s debut, the bloodroots, twinleafs, Virginia bluebells, saxifrages and countless other species of wildflowers bloom in rapid succession through April and into May. As he did with the snow trillium, Dr. Wherry had much to do with collecting, planting and nurturing many of the wildflowers that we see throughout the Preserve. Today, our curator, grounds manager and volunteers all seek to build upon his legacy of stewardship, which begins by understanding plant ecology and plant niches.

There is no place quite like the Preserve, where you can see so many species and so much variety in such a small space. I encourage you to make several trips to the Preserve between April 1 and May 15. In this brief six-week period, the Preserve changes quickly from day to day, and you can watch the woods transform from winter dormancy to full spring regalia. See you on the trails!

Cu rator’s NotebookRECENTLY UNCOVERED SEEP IN AQUETONG MEADOW WILL ENHANCE PRESERVE’S NATIVE PLANT DIVERSITYWhile clearing storm debris and invasive weeds from what will be our new Aquetong Meadow, we have uncovered a natural seep—about three-quarters of an acre where the soil often tends to have nearly permanent subsurface moisture.

It is possible that the seep, which borders the intersection of Aquetong and River roads, is fed by an underground spring. However, it is more likely fed by water runoff flowing downhill from the surrounding landscape. Or it could be a combination of spring water and surface flow.

Regardless, the saturated soil represents an excellent opportunity to diversify the Preserve’s native plant collection even further with the addition of new species of lilies, lady’s slipper orchids and fringed orchids, among others. All of these new plants are interesting, beautiful and charismatic. They are locally native but quite uncommon, so I am really

excited to be able to introduce them to the Preserve and add to the more than 700 native species—about a third of all of Pennsylvania’s native plants—that are currently growing here.

After removing invasive Japanese stiltgrass (Microstegium vimineum) and mile-a-minute weed (Persicaria perfoliate), we recently placed about a half-dozen large rocks to help slow the surface water flow and restore the seep to its natural hydrological conditions.

This spring, we will begin planting the seep. Using a combination of seeds gathered from our existing meadow and other local sources, we will also seed the rest of Aquetong Meadow and allow those seeds to germinate and grow throughout the summer. As additional plants in our Native Plant Nursery grow large enough, we will also be planting them out in the meadow. We anticipate that we will have significant plant growth by next spring, possibly some flowering in 2020 and, by 2021, a recognizable wildflower meadow.

—Jason Ksepka, Curator

Universal Access Trail Now Open, Revised Trail Map AvailableThe Preserve has just unveiled our new Universal Access Trail through Penn’s Woods to the Pond. A newly revised Preserve trail map is now available that highlights the access trail and includes other trail modifications.

The trail and the new map are the first of multiple improvements that were made possible late last year by a grant from the Foundations Community Partnership.

The trail provides greater public accessibility to the wonders of the Preserve, especially for those with physical, developmental and emotional challenges.

The revised map delineates more than two dozen well-marked trails that wind through the Preserve’s varied habitats. Covering about 4.5 miles, the trails offer a great way to experience something new each time you visit the Preserve.

To Maximize Visitor Experience, Preserve Is Developing Interpretive PlanHave you ever had an experience at a museum or national park that connected you to the resource and sparked further interest? If so, there was most likely an interpretive plan in place that helped to guide your experience.

Nearly every state park, national park, museum and heritage site has an interpretive plan. It is the key ingredient for management, strategic planning and the fulfillment of an organization’s mission.

Effective interpretation helps reveal our message to visitors in a memorable way that inspires them and encourages their stewardship. It carefully balances the needs of visitors with the needs of the resource—in our case, the needs of the Preserve and its native plant collection. Interpretive planning, meanwhile, is a collaborative process that guides the best way to reach diverse audiences through personal and non-personal efforts and media.

Bowman’s Hill Wildflower Preserve has been fortunate to receive a grant from the Pennsylvania Department of Human Services to fund this effort. This January, we began working with Dave Bucy, Ph.D., of Bucy Associates, Corvallis, Oregon, to guide us through this process. He has many years of experience in this field and is currently concluding the interpretive planning effort for Washington Crossing Historic Park.

Our interpretive plan will be created through a collaborative process involving management, staff, board members, interpretive specialists, subject matter experts and other stakeholders. It encompasses virtually every potential visitor experience from arrival to departure and even beyond. The Preserve has put together a diverse team of eight to spearhead this initiative.

The Preserve needs an interpretive plan for many reasons: to help visitors form strong connections to the Preserve and its stories, to tell our story more effectively, to expand our community, to demonstrate initiative and preparedness to potential funders, and to collaborate with management, staff, partners and the community.

The target for completing the plan is December 2019. “We are excited about working with Dr. Bucy, and look forward to this new chapter in the future of the Preserve,” says Maggie Strucker, the Preserve’s interpretive coordinator.

NOW AVAILABLE AT THE VISITOR CENTER!

PRESERVE’S NATIVE PLANT NURSERY OPENING LECTURE WILL FEATURE DR. GARY C. PAVLISFrom the Pine Barrens: The Rise of the Beloved Blueberry - A Historical Perspective

The worldwide cultivation of the highbush blueberry owes its origin to one woman living in New Jersey. Elizabeth White’s family were cranberry growers in New Jersey’s Pine Barrens. Through her dedication, perseverance and horticulture knowledge, the highbush blueberry was taken out of the woods and developed into one of the most healthy and loved fruits worldwide.

Join us for this free members-only lecture on Saturday, April 13, 10 – 11 am

Gary C. Pavlis, Ph.D., associate professor and agricultural agent at Rutgers University, has been working with the blueberry industry for close to 40 years.

Plant sale shopping following lecture from 11 am – 5 pm.

The plants we grow on-site and sell in our Native Plant Nursery play an important role in increasing the supply of local provenance plants. Complements to any landscape, a few of our favorites include:

Virginia bluebells (Mertensia virginica) The term “Spring Garden” comes to mind when picturing this native, splendid and dependable treasure of the Preserve. The new emerging purple-tinted leaf clusters, with their graceful display of flowers, make this plant a favorite of gardeners. Being ephemerals, they die back soon after blooming in early spring. However, many Virginia bluebells will have seeded, rewarding the gardener with new seedlings the following year. Easily transplanted, look for two-inch, two-leaved seedlings with purple-green coloration.

Wood poppy (Stylophorum diphyllum) Another important plant in our propagation efforts, the colorful display of the wood poppies’ sunshine-yellow flowers begin a bit later than the Virginia bluebells and last for many weeks. Wood poppies also generously produce new plants along the sides of the parent plant. One of the most encouraging characteristics of this native plant is its ability to do well in full or partial shade and to tolerate quite a bit of sun with no change in bloom production.

Golden ragwort (Packera aurea)Our final featured plant has a more defined use profile: it is an under-used groundcover. The leaf shape is very pleasing while the flowers atop the tender, straight stems have a definite woodland charm. With a deep golden yellow color, this plant blooms and grows easily in shade while quickly spreading outward in rich soil. It can spread in more difficult conditions as well. Requiring little maintenance, golden ragwort is a favorite semi-evergreen ground cover—particularly in areas where it can be allowed to spread widely.
